"The situation with the split between OpenCFD version and Hrvoje -dev version does not improve things, and it is a priority the two involved parts should really address soon, finding a way to cooperate, because, like it or not, it is the only way to go for a successful plan. Put in other words, the two parts need each other work."

I wondered when the following elements are planned to packaged in the next release of OpenFOAM:

class coupledFvScalarMatrix
library ldusolvers

I know it is annoying to be asked those question, but I really hoped ldusolvers would make it into 1.5

The situation is not as trivial as you perceive, and it is definitely not hot-headedness on my side that is causing trouble. The solution for the problem is basically OpenFOAM-Extend and parallel releases since it has proven impossible to achieve any sort of cooperation from OpenCFD with the open source development effort.

May I suggest you pose this question directly to Mr. Weller in Berlin next week - I will certainly try to do so.

But open source doesn't mean a wikipedia development model, where various participants add/remove/change things.

At the moment, I try to participate in two other open source projects -- GridEngine (SUN) and ParaView (KitWare) -- in the form of bug-fixes, RFEs etc. Some of my ideas/changes are accepted, some rejected, some modified and some just keep waiting. In the end it is the developers at SUN and KitWare who decide where it is all going. I don't see why it should be any different here.
